Effetre Streaky Denim is very streaky indeed. It is, however, not denimy at all, denim typically being neither purple nor cobalt blue in colour. Streaky Denim is one of the Effetre 'Cool Colours', a term which I have never heard explained. I used to think that these colours were so-classified because they were special batches of colour mixed from other regular production colours, and I guess for all I know that impression of mine could be true, but if it is, I wonder what this one would have in it. Maybe it's New Violet plus Light Cobalt?
Anyway, Streaky Denim is among the few of these so called 'Cool Colours' that I actually think is cool. I love Earth best, but you can't seem to be able to get that any more so it's best to just put it out of your head. In fact, I shouldn't have tempted you. Bad Melanie.
Where I used silver leaf on top of Streaky Denim, it sort of dispersed and is mostly not really visible on the bead's surface. However, when the bead is subsequently reduced and encased, you can see that the reason it was not visible on the surface was because it has spread itself thinly all over the bead. The rightmost bead in this picture has a shiny, mother-of-pearl effect under the encasement layer, and iridescent flashes of blue.
I've done this test with a lot of colours now (I think this might be colour #192 or #193) and at this point, what I am noticing is that some colours make silver spread out, some colours make it condense in on itself, and some colours don't influence its behaviour at all.
In my opinion, this colour doesn't make a great base for silver glass. The reducing silver glass frit looks washed out on top of it, and I had a hard time striking my TerraNova2 frit.
On top of Tuxedo and Copper Green, Streaky Denim separates and gets silvery around the edges. This reaction is pretty neat, and did not prepare me at all for what happened on the rest of the bead. For some reason, on top of Opal Yellow, Ivory, AND Peace, my Streaky Denim turned brown. This surprised me, and I'm not sure why it happened. I should add also that in other beads, I have used Streaky Denim on top of both Opal Yellow and Ivory without this happening. *sigh*
In spite of all this weirdness when it gets to be on top, when Streaky Denim is used as the base colour, the results are much less shocking, if not less confusing. Dots and stringer lines of Tuxedo, Opal Yellow, Ivory, and Peace on top of Streaky Denim seem not to react at all, and Copper Green's only response is to blush turquoise and separate slightly, and fail to develop the dingy army-green sheen that it had in the bead on the left.
